Improvement in pumps



aan effet WILLIAM G. BARRE-R, OF YPSILANTI, MICHIGAN'.

Letters Patent No. 108,954, dated November 8, 1870.

The Schedule referred torinthese Letters Patent and making part of the same.

To whom, tfmay concern:

Be it knownthat I, WILLIAM G. BARKER, of Ypsilanti, in the county of Washtenaw and State of Michi'- gan, have invented new and useful Improvement in a Pump; and I do declare that the following is a true and accurate description thereof, reference heing had to the accompanying drawing and to `the letters of reference marked thereon 'and heilig a part of this specilication, in which- Figure l is an elevation of 1 my pump.

Figure 2 is a vertical section of the same.

Like letters indicate like parts in each ligure.

'l he nature of this invention relates to an improved construction of pumps; and

It consists in the peculiar arrangement, with a reciprocating pump-cylinder provided with a foot-valve, ot' a bucket reciprocated alternately with and surrounding it, whereby the labor of pumping is diminished as the weight of the cylinder is made available in forcing upthe water therein.

In the drawing--- A represents a metallic tube forming-the'pump-cylinder, expanded at the lower end, where it receives a hollow wooden plug, B, provided on its upper surface with a foot-valve, O.

-On the lower end of thcplug is secured an annular gasket of' leather orl rubber, D, projecting outwardly from the edge thereof.

E is a standard erected on the well-curb, to which is pivoted the lever or brake F to a fork, in which the upper end of the cylinder is pivoted at a given distance from the fulcrum.

G is a cylindrical vessel or bucket surrounding the plug B, and is in like manner provided with a footvalve, H.

I are connecting-rods, whose lower `ends are piv.

oted to the bucket, and the upper are pivoted to the brake, at the other side of the standard, at an equal distance from the fulcrum, so that it will travel the same ,distance as the cylinder, but in-an 'opposite direction. llhc Ipacking attire end of the plug pre vents leakage between it and the bucket.

It will be seen that, as the bucket and cylinder r e cede from each other, the former fills, and, as 'they come together, the water contained in the bucket is expelled,f passing up through the cylinder to' a dis charge-spout on top, while the weight of the cylinder is made available for forcing up the water. Also, that the travel or throw of the lever is one-half less than in the ordinary single-acting pump'.

I do not wish to confine myself to the usegof a metallic pump-cylinder solely, as in shallow wells wooden ones answer as well, besides costing much less; n or to the locationof the fulcrum lmidway between the cylinder and upper ends of the connecting-rods, as, when the cylinder is long and heavy, it may be placed nearer to the fulcrurn, whereby the throw of the cylinder will be diminished, and that of' the bucket increased.

What I claim as my invention, and desire to secure by Letters Patent, is-

lhe combination, with the reciprocating cylinder A, provided with the hollow plug B, valve O, and packing D, of Vthelbucket G, surrounding the' same and reciprocating alternately therewith, as and for the purpose herein set forth.

WILLIAM C. BARKER.
